THE REVOLUTION BEGINS! Explosions rip across the Earth—and all signs of blame point to OPTIMUS PRIME and the TRANSFORMERS! G.I. JOE refuses to go quietly—and they assemble heroes big enough to stop the invaders! ACTION MAN and M.A.S.K. fight for humanity—but where do ROM and the MICRONAUTS stand? Celebrating more than a decade of stories by IDW and HASBRO, this unprecedented bi-weekly event draws everything together—and leaves nothing standing. The REVOLUTION is here—TAKE A STAND!

A Hasbro Comic Book Event of epic proportions! The TRANSFORMERS are under attack from COBRA, G.I. JOE's greatest enemy! As Earth joins the intergalactic community, a massive explosion threatens the peace! A new COBRA—led by the worst villains to ever tangle with G.I. Joe, M.A.S.K.:Mobile Armored Strike Kommand, and the Transformers—is invading Cybertron, and only Scarlett, Optimus Prime, the Joes, and the Autobots can save two worlds! It's a race to the finish as good fights evil! Will our heroes win, or will Cobra DESTROY ALL TRANSFORMERS?!?

The end is nigh! Unicron, a planet-sized being that devours other worlds, has set its sights on Cybertron and all of its colonies–including Earth! Optimus Prime, Bumblebee, and their friends must unite every Cybertronian, Earthling, and ally they have to stand against this threat to all existence. But why is Unicron hell-bent on destroying Cybertron–what original sin did Optimus Prime's ancestors commit to earn this wrath? It's an all-out battle against extinction as the world-destroying, universe-shattering threat of Unicron is on its way.
